Specification of Letters Patent.

Application filed April 30, 1917. Serial No. 165, 57.

To all whom it may concern:

Be it known that I, JAcoB Lnwis Num- LINGER', a citizen ofthe United States, residing at 'Blackwood, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in Gates for Elevator-Landings, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in gates for elevator landings and 1t is an object of the invention to provide novel and improved means whereby a gate may be caused to assume, an open position when the elevator approaches a landing and whereby said gate automatically assumes a closed position when the elevator moves away from the landing.

It is also an object of the inventlon to provide a device of this general Character especially designed and adapted for use 1n connection, with elevators or hoists in IIllIling operation and wherein fans or arms are employed to bring the hoistor elevator to a stop at a predetermined landing together with novel and improved means under control of the fans or arms whereby the elevator or hoist as it approaches the landing causes the gate to assume an open position.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my 1mproved gate for elevator landings whereby certain important advantages are attained and the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as Wlll. be hereinafter more fully set forth. a

The novel features oftheinvention will hereinafter be definitely claimed.

In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the accompanying drawings, wherein Figure 1 is a fragmentary view partly 1n elevation and partly in section illustrating a gate structure arranged in accordance with an embodiment of my invention Fig. 2 is a view partly in section and partly in elevation of the gate structure as herein embodied and at substantially right angles to the disclosure in Fig. 1; I

Fig. 3 is an enlarged fragmentary vlew partly in section and partly in elevatlon illustrating one of the tubular members and.

a shoe coacting therewith as herein embodied together with the parts coacting with the shoe; 7 l

Fig. 4; is a. transverse sectional view taken through a tubular member; and

Fig. 5 is a view partly in section and,

pivotally supported by the structure S at opposite sides thereof and at a predetermined distancebelow the landing are the rock shafts 1 provided with the upstanding arms or fans 2 which, when swung inwardly, serve to limit the downward movement of the elevator or cage C so thatthe same will be properly alined with the landing L.

As herein disclosed, the structure S at op posite sides thereof and intermediate the shafts 1 is provided with the arm 3 pivotally mounted at substantially its longitudinal center. ()ne end portion of the arm 3 is operatively engaged, as at 4;, with an arm or fan 2 at one side. of "the structure S 'while the opposite end of the arm 3 is operatively engaged, as 21th, with an arm or fan 2 at the opposite side of the structure By this arrangement it will be perceived that the shafts 1 will be rocked in unison but in reverse directions.

Coacting with each set of fans or arms 2 at a side of the structure S is a pivoted arm 6 operatively engaged with one of the con necting members, such as 5, and the upper end portion of said arm 6 is providedwith an operating member 7 provided with a hand grasp 8 whereby the arms or fansQ may be manually operated to cause the same to assume an operative or inoperativeposition relative to the cage orelevator G.

The structure S is provided at opposite sides of the landing L with the vertically disposed tubular members 9 provided with the elongated slots 10. The lower end of each of the tubular members 9 is rotatably engaged with an upstanding pin 11 suitably supported by the structure S while theupper portion of the tubular member 9 is ex tended through an annular member 12 car ried by a strip 14 also operatively engaged with the structure S at a predetermined point above the landing L.

Loosely mounted Within each of the tubular members 9 is a head or block provided with a shoe 16 extending through the slot 10 and having its upper edge substantially horizontal. The lower portion of the tnbular member 9 1s provided with a rock arm 17 with which is pivotally engaged a rod 18 -.also operatively engaged with one of the fans or arms 2. V

When the armsor fans 2 are moved 1nwardlyio engage the elevatoror cage C the tubular member 9 will be given a quarter 'is also directed through the coil spring 22 I arranged within the tubular member 9. The

springv 22 is provided at its oppositeends withthe hook members 23 engaged with certain of the links of the chain whereby said chainis maintained taut.

The outer end of the chain or flexible member21 is provided With a clevis 24 to with the gates which are engaged the chains 25 which extend in opposite directions and over the guideepnlleys 26 suitably mounted upon the structure 8.. The chains 25 are engaged G mounted for verticalmovement and whereby it will be perceived that as the shoe 16 is forced downwardly the gates G will assume an open position. It

will also be-self-evident that. whenthe cage or elevator C, moves upwardly the weight of the gates. G will cause the same to move downwardly by gravity and assume a. closed position. 7

While the chains, 25 maybe secured to the gates G in any desired manner, I prefer to l have thechains engaged with the elevises 27 portions of the pivotally engaged with the upper marginal gates G adjacent the opposite ends thereo V It is also to be noted that the gates G have thelr opposite end port ons engaged Within suitable guideways 28.

Fror'n the foregoing description, it is thought to be obvious that a gate for elevator landingscon'structed in. accordance with my invention is of an extremely simple and con'lparatively inexpensive nature and is particularly well adapted for use by reason of'the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.

I claim:

In combination with an elevator and a shaft therefor provided with a landing, a vertically movable gate co-acting with the landing, a vertically disposed member mounted for swinging movement and movable into and out of the path of travel of the elevator for limiting the movement of the elevator within the shaft in one direction, a tubular member disposed in the same general direction as the shaft and mounted for rotary movement, said member being provided with a longitudinally directed slot, a block slidably engaged within said memberand provided with a shoe extending through the slot of the tubular member, said shoe being adapted to extend within the line of travel or" the elevator, a rock arm carried by said last named member, a rod pivotally engaged with the rock arm and 'operatively engaged with the vertically disposed. member whereby swinging movement of the member serves to rock the rotatable member about its longitudinal axis, means for moving the vertical member into or out of the line of travel of the elevator, and a flexible connection between the block and the gate for moving said gate into an open position when the shoe is caused to move when engaged with the elevator, said flexible connection extending within the tubular member through the upper end thereof.

In testimony whereof I hereunto aiiix my signature in the presence of two witnesses.
